EDWIN SCOTT, OF NEWBERRY, INDIANA.

ACETYLENE-GAS GENERATOR.

To all whom 'it 'may concern:

Be it known that I, EDWIN ScoTT, a citizen of the UnitedStates, residingat Newberry, in the county of Green and St-ate of Indiana, have inventedcertain'new and useful Improvements in Acetylene-Gas Generators, ofwhich the following is a specication.

This invention relates to an acetylene gas generator, belonging to thattype wherein the lower 'end and inlet of the gas-holder.

r accompanying drawings, made a parthereof, in which- Figure 1 is acentral vertical sectional view through the gas generator.V F ig. 2 isan enlargedfragmentary detailsectional view of the discharge end of thecarbid hopper and the valve for controlling the discharge openingtherein. Fig. 3 is a fragmentary detail view in side elevation of thelower end of the hopper and the valve for controlling the dischargeopening therein.

The gas generator herein shown may be located above the ground, but inorder to insure safety to surrounding buildings in congested districts,and to prevent the water within the generator from freezing, I find itmore convenient to place the same within a pit located in the ground.

10 represents the pit, 11 t-he surface of the ground, and 12 the wall ofthe pit which is usually and preferably composed of concrete. The carbidcontainer consists of a receptacle or hopper 15 which is locatedcentrally within the pit 10, and is mounted upon a frame-work, composedof a plurality, usually three or four, of flat-iron bars 16, andattached to the upper end of said bars are the angle-irons 17 which forma support for the carbid-receptacle 15. The bars 16 are bent outwardlyand project and rest against the inner wall of the pit 10 as Specicationof Letters Patent.

Application led December 19, 1911.

Serial No. 666,815.

shown, and the bars 16 are inclosed by means of a skirt 18, andthechamber 'formed by said skirt receives the carbid discharged from thecarbid-receptacle. The process of generating gas is conned within thearea inclosed by the skirt 18 and through its formation t-he gas isdirected to and discharged into the gas-holder 20.

The carbid-receptacle 15 is provided with an opening 22, covered by ascrew-cap 23 through which the carbid is introduced, and the lower endof said receptacle is contracted, as at 25 and terminates in a sleeve 26that forms the discharge opening. Suspended below and locatedconcentrically with the discharge opening of the carbidreceptacle is acone or spreader 30 adapted i to separate and distribute the-carbid,which cone is maintained in proper position with relation to .saiddischarge opening by means of a plurality of braces 31. A collar 33surrounds the sleeve 26 and has longitudinal movement on said sleeve.The collar 33 when occupying its lowest position rest-s upon the cone 30whereby the discharge opening of the carbid-receptacle is closed, andwhen said collar is elevated the discharge opening of said receptacle isopened.

The movement of the collar 33 is effected by means of the gas-holder 20operating through the vertical rods 410 arranged within and at oppositesides of the carbidreceptacle 15. These rods engage the levers 11 whichare pivotally secured to the standards 42, the levers 41 engaging thecollar 33 through suitable links 44. When sufficient gas has beenwithdrawn from the gasholder 20 to allow the same to descend andcontract upon the upper ends of the rods 40 the collar 33 will beelevated and'allow a fresh charge of carbid to be discharged into thewater in the pit, and when suiiicient gas has been generated to elevatethe gas-holder 20 to relieve the pressure from the rods 40, the collar33 will descend to its lowest position and engage the surface of thecone 30 and stop th discharge of carbid from the carbid-receptacle 15.This downward movement of the collar 33 is eifected by placing thefulernms of the levers l1 in close proximity to the rods 40, so that theleverage afforded said collar is sufficient to elevate the rods 10 andthe cross-bar 4.5. In order to impart uniform movement to both of therods 40 they are tied together at the top by means of a cross-bar 45.The gas-holder 20 t The gas-holder 20 may be entirely re moved from thepit by means of a suitable windlass or block-and-tackle (not shown)located above the pit, the rope leading from the hoisting deviceengaging the eye 60 secured to the central portion of the gasholder.After the gas-holder is removed the carbid-receptacle l5 may be removedby making suitable attachment with the crosse bar 45.

Having thus fully described my said invention, what I desire to secureby Letters Patent, is-

l. An acetylene gas generator comprising a water holding generatingchamber, a car bid-receptacle located within and above the water in saidchamber and provided with a discharge opening, a spreader located belowand in line with said discharge opening, a hollow valve extending aroundsaid dis charge opening in said carbid-receptacle, a vertically disposedrod arranged at each side of said valve and actuated by said gasholder,and levers pivotally engaging the rods and with the opposite sides ofsaid valve for exerting a uniform pull on said valve.

2. An acetylene gas generator comprising a water holding generatingchamber, a carbid-receptacle located within and above the water in saidchamber and provided with a Copies of this patent may be obtained fordischarge opening, a spreader located beiow and in line with saiddischarge opening, a hollow valve extending around said dischargeopening in said carbid-receptacle, a vertically disposed rod arranged ateach side of said valve and actuated by said galsholder, and `leverspivotally engaging the rods and with the opposite sides of said valvefor exerting a uniform pull 0n said valve, an open bottom gas-holderinclos-Y ing said carbid-receptacle, and a skirt encompassing the entirearea of the pit and extended up above the water and adapted to directthe gas into said gas-holder.

3. An acetylene gas generator comprising a water holding generatingchamber, a carbid-receptacle located within and above the water in saidchamber and provided with a discharge opening, a spreader located belowand in line with said discharge opening, a hollow valve extending aroundsaid discharge opening in said carbid-receptacle, a vertically disposedrod arranged at each side of said valve and actuated by said gasholder,levers pivotally engaging said rods, and links interposed and pivotallyconnecting the ends of the leversand valve to provide compensatingadjustment between said levers and valve. t

In witness whereof, I have hereunto set my hand and seal atIndianapolis, Indiana, this 7th day of December, A. D. one thousand ninehundred and eleven. i
